FlLLET-CUTTING MACHINE.

SPECIFICATION forming part of Letters .Patent No. 676,728, dated J une18, 1901. Application filed October 20, 1900. Serial No. 33,718. (Nomodel.)

To LZ/ whom t may concern:

Beit known that we, JOHN O. SCHMITT and ELMER E. WEBSTER, citizens ofthe United States, residing at Akron, in the county of Summit and Stateof Ohio, have invented a certain new and useful Improvement inFillet-Cutting Machines, of which the following is a specification.

Ourinvention has relation to improvements 1o in machines for cuttingthat class of fillets composed of leather substantially triangular inoutline and used for rounding the inner angles of wood patterns formetallic castings.

The object of our invention is to produce a new and efficient machinefor rapidly and accurately cutting those iillets in which the knifeshall be capable of being raised from the platform over which theleather strip runs to permit of the easy and rapid introduction of thestrip, in whichA the knife shall be detachable to permit of thesubstitution of one having a diiferent angle at its cutting-surface andfor sharpening when needed, which shall have adjustable gages to guideand conform to different widths of strips, and in which the knife-armbearings shall be adjustable to move it accurately to position and tocoinpensate for wear.

To the aforesaid object our invention consists in the peculiar and novelconstruction, arrangement, and combination of parts hereinafterdescribed and then specifically pointed out in the claims, referencebeing had to the accompanying drawings, forminga part of thisspecification.

In the accompanying drawings, in which similar reference-numeralsindicate like parts in the different views, Figure 1 is a plan; Fig. 2,a side elevation, and Fig. 3 a front elevation looking from the left ofFig. 2.

Referring to the gu res, l is a metallic base of irregular outline, asshown, provided with screw-holes 2 2 to permit of its being attached toa table or bench. At the back of this base arise two oppositely-disposedposts 3 3, having opposite screw-threaded openings in their tops inwhich are iitted two pivot-screws 44, with inner conical ends, and eachprovided with a jam-nut 5 for securing them against 5o loosening. At thefront of the frame and integral therewith is a small platform 6, withits face smoothly planed and on which the leather strips slide incutting., Pivotally mounted between the screws 4 is an arm 7, having atthe free end a cross-bar 8, slotted vertically at each side of thecenter and adapted when swung down to rest substantially centrally abovethe platform G. Beneath the cross-bar 8 are oppositely-disposed guides9, having bosses that enter and slide in the slots 6o in the cross-barS, these bosses and guides having vertical screw-threaded openings inwhich run thumb-screws 11, having washers 12, that bear on the upperface of the crossbar 8. By this arrangement these guides 9 65 arelongitudinally adjustable to adapt them to the width of the strips to becut.

The arm '7 is made in skeleton form, havL ing side pieces connected atthe front by the before-mentioned cross-bar 8 and at the back 7e betweenthe pivots 4 by an integral rod 13 and intermediately two cross-bars 1415, the latter bent downward in the center to form a rest for the knife,and between these and curved upward a cross-bar 16. Through the 7 5'bars 14 and 16 are screw-threaded openings in which mesh screws 17 1S,respectively. Resting on the bars 14 15 and under the bar 1G is theknife 19, which is in cross=section in form of a flattened V, the twosides curved 8o upward slightly to give the desired shape to the fillet,and with its front edge sharpened and resting directly back of theplatform 6, with the point of the V normally slightly be low the surfaceof that platform.

The machine is secured to a rm table or bench, and in operation, theguides 9 being adjusted to the desired width, the arm and knife areraised and the end of a strip of leather passed from the front over theplat- 9o form 6 until its end can be grasped by the hand or pliers. Theknife is then swung down and the strip drawn from the front back againstthe edge of the knife, which cuts the desired fillet. To enable thestrip of leather to be thus drawn, the platform 6 and knife 19 areoffset to one side, so that they may ex; tend over the edge of the tableor bench.

We claim as our invention-- 1. An improved fillet-cutter embodying a roebed, having a platform for the strip to be cut, guides to regulate thedirection of the strip,

a swinging knife-carrying arm arranged to rest above and adjacent tosaid platform and means for adjusting the pivots of said arm,substantially as shown and described.

2. An improved fillet-cutter embodying a bed, having a platform for thestrip to be cut, a swingingarm arranged to rest adjacent to saidplatform, adjustable guides connected with said arm to regulate thedirection of said strip, and a V-shaped knife adj ustably mount: ed insaid arm arranged to rest adjacent to said platform and adapted toengage and cut a strip passing thereover, substantially as shown anddescribed.

3. An improved fillet-cutter having'a bed with an offset platform forthe passage of the strip to be cut, a swinging arm pivotally lover saidplatform substantiallyfas shown and described.

In testimony that We claim the above we `hereunto set our hands in thepresence of two subscribing witnesses.
